Statistical hydrology for evaluating peatland water table sensitivity to simple environmental variables and climate changes application to the mid-latitude/altitude Frasne peatland (Jura Mountains, France)

Restoration and meteorological variability highlight nested water supplies in middle altitude/latitude peatlands: Towards a hydrological conceptual model of the Frasne peatland, Jura Mountains, France

“…Over the long term, such a nested model should therefore be useful to evaluate and predict further climate change impacts that are still difficult to model mechanistically in such mosaic‐like ecosystems (Bertrand et al, 2021). The predicted increase of winter precipitation in northern midlatitudes (Brulebois et al, 2015; Shulka et al, 2019) could further imply a greater proportion of delayed regional groundwater in the coming decades, especially during vegetation development in summer.…”

“…At the whole ecosystem scale, this compartment is recognized to favour (1) superficial horizontal flows in particular during stormflow in wet periods (Holden & Burt, 2003); (2) a high water storage capacity after desaturation, due to greater porosity in this layer (Boelter, 1965;Oosterwoud et al, 2017); and (3) therefore control the complex discharge behaviour depending on preceding hydrological conditions (Wilson et al, 2010). For the Forbonnet bog, Bertrand et al (2021) identified a threshold depth of À19 cm near the central part of the bog consistent with the acrotelm/catotelm boundary and provides an estimation of the upper reservoir dimension.…”

“…For instance, about 25% of its original surface is currently used for forestry and agriculture (Page & Baird, 2016). Anthropogenic disturbances are exacerbated by climate change: increase of air temperature (Shulka et al, 2019) and modification of rainfall seasonality (Trenberth, 2011) both impact WTD (Bertrand et al, 2021) and thus the ecohydrological functioning of peatlands.…”

Analysis of hydrology parameters in a tropical wetland as an early approach to identify a drought risk in a peatland area

“…Understanding the situation and assessing the wetland well is necessary to measure and evaluate the wetland situation. It can be done by analyzing wetland hydrology parameters and their correlation to water table elevation [26][27][28]. Due to the necessity to mitigate change conditions in a wetland, it is common to know that either flood or drought will derive a difficult situation both in a wetland and a peatland but especially for a peatland, drought condition is severe.…”

The information system of the French Peatland Observation Service: Service National d'Observation Tourbières – A valuable tool to assess the impact of global changes on the hydrology and biogeochemistry of temperate peatlands through long term monitoring

“…Binet et al (2013) used WTD and the soil‐meteorological datasets from the La Guette site to develop a model highlighting the sensitivity of evapotranspiration to peatland plant community composition. Bertrand et al (2021) evaluated WTD to meteorological parameters and simulated future WTD under various IPCC scenarios. Bernard‐Jannin et al (2018) used the WTD dataset from La Guette to set up a model describing the dissolved organic C (DOC) concentration in peat water.…”
